How do I return a char array from a function?

I think you’re reading those stats incorrectly. They show that Python is up to about 400 times slower than C++ and with the exception of a single case, Python is more of a memory hog. When it comes to source size though, Python wins flat out. My experiences with Python show the same definite trend … Read more
Possibly: This would read in and ignore everything until EOF. (you can also supply a second argument which is the character to read until (ex: ‘\n’ to ignore a single line). Also: You probably want to do a: std::cin.clear(); before this too to reset the stream state.
Your bracketing is broken. The net result is that you are attempting to define your main function inside ciong. And C++ does not support nested function definitions. Hence the compiler error. The code should be: And there are other bugs. For example, you meant cout << ciong(n).
You need to include
std::endl is a function template. Normally, it’s used as an argument to the insertion operator <<. In that case, the operator<< of the stream in question will be defined as e.g. ostream& operator<< ( ostream& (*f)( ostream& ) ). The type of the argument of f is defined, so the compiler will then know the exact overload of the function. It’s comparable … Read more
Even if you’re not allocating memory directly, it happens under the hood in vector code and you most likely corrupted some portion of memory by writing where you are not supposed to. The most likely reasons I can think of are: Writing to an element that is out of bounds Using a pointer/reference to an element that … Read more
In C#, there is a nice syntax sugar for fields with getter and setter. Moreover, I like the auto-implemented properties which allow me to write In C++ I have to write Is there some such concept in the C++11 allowing me to have some syntax sugar on this?
I am trying to make a function that returns double the integer number that I will pass to it. I am getting the following error message with my code: declaration of ‘int x’ shadows a parameter int x; “ Here is my code:
